Abstract

A lighting directional sign includes a L-shaped illuminating unit including a casing, an illuminator protected by the casing, and an electric input connector provided on the casing and electrically connected with the illuminator, wherein the illuminating unit is disposed in a lamp chamber of a vehicle signal light and electrically connected with a power outlet of the vehicle signal light. The illuminating unit is aligned as an arrowhead shape in such a manner when the vehicle signal light is switched on, the illuminating unit is automatically switched on in order to signify the further motion of the vehicle.

Claims

1. A lighting directional sign for vehicle signal light comprising a base plate, a power outlet, and a lamp cover for covering said base plate so as to define a signal light chamber between said base plate and said lamp cover;

and

a L-shaped illuminating unit, which is disposed in said signal light chamber of said signal light, with a casing, an illuminator protected by said casing, and an electric input connector provided on said casing and electrically connected said illuminator to said power outlet of said base plate, wherein said illuminating unit is aligned as an arrowhead shape in such a manner when said signal light is switched on, said illuminating unit is automatically switched on in order to signify a further directional motion of said vehicle; and

three rod-like projections outwardly protruded from an inner surface of said lamp cover for engaging with three mounting plates, each having an engaging slot, extended from three corners of said illuminating unit respectively, so as to substantially mount said illuminating unit on said lamp cover.

2. A lighting directional sign for vehicle signal light comprising a base plate, a power outlet, and a lamp cover for covering said base plate so as to define a signal light chamber between said base plate and said lamp cover;

and

a L-shaped illuminating unit, which is disposed in said signal light chamber of said signal light, with a casing, an illuminator protected by said casing, and an electric input connector provided on said casing and electrically connected said illuminator to said power outlet of said base plate, wherein said illuminating unit is aligned as an arrowhead shape in such a manner when said signal light is switched on, said illuminating unit is automatically switched on in order to signify a further directional motion of said vehicle, wherein said casing of said illuminating unit has a shelter having a transparent front surface and a protective layer sealedly attached to said shelter in a water tight manner, wherein said illuminator is disposed in a lighting chamber defined between said protective layer and said shelter, wherein said illuminator has a L-shaped circuit board securely mounted on said protective layer and covered by said shelter, and a plurality of LEDs electrically and spacedly mounted on said circuit board and align to form a L-shape; and

three rod-like projections outwardly protruded from an inner surface of said lamp cover for engaging with three mounting plates, each having an engaging slot, extended from three corners of said illuminating unit respectively, so as to substantially mount said illuminating unit on said lamp cover.

3. A lighting directional sign for vehicle signal light, as recited in claim 2, wherein each of said projections has a first portion and a second portion and each engaging slot has a diameter slightly larger than a diameter of said second portion of said projection and smaller than a diameter of said first portion thereof in such a manner said mounting plate is biased against a top end of said first portion of said projection when said projection is inserted into said engaging slot to mount said illuminating unit on said lamp cover.

4. A lighting directional sign for vehicle signal light, as recited in claim 3, wherein each top end of said second portion of said projections is melted after said respective mounting plate is mounted thereon, so as to firmly lock up said illuminating unit on said lamp cover.

5. A lighting directional sign for vehicle signal light comprising a base plate, a power outlet, and a lamp cover for covering said base plate so as to define a signal light chamber between said base plate and said lamp cover;

and

a L-shaped illuminating unit, which is disposed in said signal light chamber of said signal light, with a casing, an illuminator protected by said casing, and an electric input connector provided on said casing and electrically connected said illuminator to said power outlet of said base plate, wherein said illuminating unit is aligned as an arrowhead shape in such a manner when said signal light is switched on, said illuminating unit is automatically switched on in order to signify a further directional motion of said vehicle, wherein said casing of said illuminating unit has a shelter having a transparent front surface and a protective layer sealedly attached to said shelter in a water tight manner, wherein said illuminator is disposed in a lighting chamber defined between said protective layer and said shelter, wherein said illuminator has a L-shaped circuit board securely mounted on said protective layer and covered by said shelter, and a plurality of LEDs electrically and spacedly mounted on said circuit board and align to form a L-shape, wherein said electric input connector has a conductive wire electrically extended from said circuit board and detachably connected to said power outlet of said signal light; and

three rod-like projections outwardly protruded from an inner surface of said lamp cover for engaging with three mounting plates, each having an engaging slot, extended from three corners of said illuminating unit respectively, so as to substantially mount said illuminating unit on said lamp cover.

6. A lighting directional sign for vehicle signal light, as recited in claim 5, wherein each of said projections has a first portion and a second portion and each engaging slot has a diameter slightly larger than a diameter of said second portion of said projection and smaller than a diameter of said first portion thereof in such a manner said mounting plate is biased against a top end of said first portion of said projection when said projection is inserted into said engaging slot to mount said illuminating unit on said lamp cover.

7. A lighting directional sign for vehicle signal light, as recited in claim 6, wherein each top end of said second portion of said projections is melted after said respective mounting plate is mounted thereon, so as to firmly lock up said illuminating unit on said lamp cover.
